value in the variable expires

[Guest]

I have 2 forms. in form1 i declared a public variable in which a value is
stored. then i goto form2 . (for this is create an object of form2 in form1.)
when i go to form2 there is call form1. when i come to form1 the value stored
in the variable decalred in form1 gets lost. how can i retain those values?

First forms are just classes like most things in .Net. It would seem that
you need to pass a reference of form1 to form2 so that from form 2 you can
access the public variable.

public class Form2 : Form
{
public Form2(Form1 form1)
{
form1.YourPublicVariable ....
}
}

First ask yourself if the public variable on Form1 really belongs to Form1.
Perhaps you should be passing a class that holds this variable to each of
your forms. What is this public variable? Is Form1 the main form of your
application so it will always be instansiated?
